## Title
Detachable whistle

## Abstract

Disclosed technology allows a whistle to be magnetically detachable from a base portion, such as a finger grip. Some embodiments comprise a whistle component comprising a first magnetic member and a base component comprising a second magnetic member, such that the first and second magnetic members are magnetically attracted to each other. The whistle component can be detachable from the base component by breaking a magnetic bond between the first and second magnetic members. At least one of the first and second magnetic members can be at least partially covered by a non-magnetic material such that the non-magnetic material separates the first and second magnetic members when the whistle component is magnetically coupled to the base component. The first magnetic member can be contained within a cavity of an adaptor that is attached to the whistle, or within the whistle itself.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 15/078,239, filed on Mar. 23, 2016, which claims the benefit of U.S. Provisional Application No. 62/138,879, filed on Mar. 26, 2015, both of which are incorporated by reference herein in their entirety.


FIELD
This disclosure relates to whistles, particularly whistles used by referees during sporting events, such as finger whistles and whistles that can be detached from and reattached to a base portion.
BACKGROUND
A whistle is typically used by referees, umpires and other officials in various sports, events, and games to signal the start and stop of action and announce penalties or goals. Traditional sports whistles range in style and type. Some have a metal body or case with a ball inside and are called a pea whistle. Others have a plastic body with sound chambers and are called “pea-less” whistles. Many whistles can be held in the hand or have an attached ring that can be clipped to a lanyard or tied to a string. Lanyards are typically worn around the neck but some are knotted and held in the hand or worn on the wrist. Other whistles, referred to as “finger whistles” are permanently attached to a ridged, but bendable metal bracelet type sleeve that is typically contoured to be worn around or clamped to the index and middle fingers.
To use a whistle attached to a lanyard worn around the neck, an umpire or official must first locate it with a free hand, grasp it in the free hand, position it in the free hand, and insert it into the mouth.
An advantage of a lanyard mounted whistle is that after inserting the whistle in the mouth, both hands are free to signal a foul or goal or to direct play while the whistle is being blown.
An advantage of a finger whistle or sleeve mounted whistle is that because of its fixed position on the fingers, it is quickly accessible and the free hand is simply moved to the mouth and the whistle inserted the mouth.
A disadvantage of using a finger whistle is that it requires that the umpire leave the hand close to the mouth while blowing the whistle which prevents the use of the hand and arm for the purpose of signaling a foul or announcing a goal while the whistle is being blown.
It is possible to remove the sleeve and whistle from the bare fingers with the mouth, however when a finger whistle is worn on a gloved hand, the process of removing it with the mouth is sometimes difficult or impossible and requires the hand to remain near the mouth or the use of the other hand to remove the whistle and sleeve from the gloved finger. This process delays the use of the hand or hands for signaling or directing play.
Another advantage of a whistle attached to a lanyard and worn around the neck is that after blowing the whistle, it permits the user to simply release the whistle from the mouth and let it drop, knowing that it is retained by the lanyard.
Another disadvantage of the sleeve mounted finger whistle that has been removed from the fingers and held in the mouth, is that after blowing, it is sometimes difficult or impossible to place the sleeve back on the fingers or gloved fingers using just the mouth and sometimes requires the use both hands to reinstall it back on the fingers. When this occurs it must be held in the mouth until both the hands are free. If the whistle is held in the mouth, the large sleeve and whistle makes it difficult to talk and verbally direct play or announce the foul especially if the hands are in use catching a ball or replacing a flag or restraining a player.
While the lanyard mounted whistle is convenient to use and does not encumber the hands once located and inserted in the mouth, it is sometimes difficult to locate and grasp in the hand while running since it is free to swing around the neck and occasionally flips over the shoulder or becomes tangled on clothing, a pen in the front pocket of a shirt or jacket, or an ear.
A sleeve mounted finger whistle is quickly accessible however it encumbers one hand during use and is difficult to remove from the fingers with the mouth should the hand and fingers be needed.
A whistle simply held in the hand, or a whistle attached to a lanyard and held in the hand, or a whistle attached to a lanyard designed to be worn around the wrist all share similar advantages or disadvantages of the lanyard mounted whistle worn around the neck or the finger sleeve mounted whistle.
SUMMARY
Disclosed herein are embodiments of devices comprising a whistle that is magnetically held to a sleeve, such as a finger sleeve, and that is detachable from the finger sleeve by breaking the magnetic bond, such as by pulling on the whistle with the mouth while holding the sleeve with a hand, and reattachable to the finger sleeve by re-engaging the magnetic bond. Also disclosed are components of such devices and methods related to such devices.
The whistle can have a permanently attached or affixed magnet that holds it to a metallic finger sleeve or a non-metallic finger sleeve with a metallic component, or the whistle can have a permanently attached or affixed metallic component that holds to a magnet that is permanently attached or affixed to a finger sleeve, or the whistle and/or the finger sleeve can comprise one or more magnets. The terms “permanently affixed,” “permanently attached,” “permanently adhered,” “affixed,” “attached,” “adhered,” and similar terms as used herein mean connected, either directly or using one or more intermediate components or substances, in such a way so as to be not readily disconnectable during ordinary use (e.g., by pulling the whistle with the mouth or while the user is running), but possibly disconnectable using a tool (e.g., a screwdriver) and/or with sufficient brute force, and the terms include the use of an adhesive or a mechanical fastener to connect components together, as opposed to the use of a readily detachable magnetic attraction to temporarily couple components together.
Some embodiments comprise a separate component or adapter comprising a magnet or metallic component permanently attached or affixed that is contoured to fit over and/or be attached to an existing whistle (such as a Fox40® plastic whistle), thereby providing the same capability to be detached from a finger sleeve with the mouth.
The whistle can comprise an existing plastic whistle (such as a Fox 40® plastic whistle) that can be easily modified to receive a magnet or magnetic component that can be used in conjunction with a metallic finger sleeve or a non-metallic finger sleeve fitted with a metallic base or magnet that provides the same capability for the whistle to be detached from a finger sleeve, such as with the mouth.
Disclosed embodiments provide advantages of a conventional finger whistle, but eliminate the need to remove the finger sleeve portion from the fingers when the whistle portion is used in the mouth while the hands are not adjacent the mouth. Disclosed embodiments also provide advantages of a lanyard whistle by allowing quick access to the whistle without encumbering the hands and quick placement back on to the finger sleeve after use.
Also disclosed are adapters for magnetically coupling a whistle to a finger sleeve. The adapter can comprise a structural component configured to be affixed to either the whistle or the finger sleeve, and a magnet or a metallic component affixed to the structural component and configured to be magnetically coupled to the whistle or to the finger sleeve. In some embodiments, the adapter comprises a magnet that is configured to be magnetically coupled to a metallic component of the finger sleeve or to a metallic component affixed to the finger sleeve. In some embodiments, the adapter comprises a magnet that is configured to be magnetically coupled to the whistle, to a metallic component of the whistle, or to a metallic component affixed to the whistle.
Also disclosed are sleeve assemblies for detachably mounting a whistle. Such an assembly can comprise a sleeve component configured to fit around a portion of a hand, such as a finger sleeve, for holding the assembly with the hand, and a coupling component configured to detachably couple a whistle to the sleeve component via a magnetic bond. In some embodiments, the coupling component comprises a magnet. In some embodiments, the coupling component comprises a receiver that is configured to be affixed to or fit around a whistle to secure the whistle to the receiver. For example, the receiver and the sleeve component can be detachably couplable together via a magnetic bond.
In some disclosed embodiments, one or more magnets and/or magnetic materials are partially or fully encased or enclosed within a polymeric material, which can act to secure the magnets/magnetic materials to the respective component of the whistle assembly.
In some embodiments, the whistle and the adaptor component that holds one of the magnets and/or magnetic materials are integrally formed or are manufactured as a single unit. For example the whistle housing can include two halves that are fixed together during manufacturing, and the two halves can include a portion that forms a housing for one of the magnets, such that when the two halves are secured together they contain the magnet.
The foregoing and other objects, features, and advantages of the disclosed technology will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures.

DETAILED DESCRIPTION
As shown in FIGS. 1A and 1B, an exemplary embodiment can comprise a whistle 1, permanently affixed to a magnet 2, which permits the whistle to be temporarily held to the metallic finger sleeve, or grip, 3, until it is ready to be grasped, such as by the mouth, and detached from the sleeve, as shown in FIG. 1B, such that it can be blown when apart from the sleeve. After use, the whistle with the magnet affixed is easily placed back onto the metallically attractive sleeve component by moving the fingers with the sleeve to the mouth and placing the whistle back on the sleeve component. The whistle with the affixed or attached magnet is held in place on the sleeve by the attraction of the magnet to the metallic sleeve component until it is ready to be detached again.
FIG. 2A and FIG. 2B shows an embodiment wherein the magnet 2 is permanently adhered to the whistle body or case 1 with an adhesive 4, such as an epoxy or other product that provides permanent adhesion between the magnet and the body of the whistle.
As shown in FIG. 3A and FIG. 3B, the magnet 2 can also be permanently affixed or connected to the whistle 1 with a mechanical fastener or connector 5, such as a screw, bolt or rivet.
FIG. 4A and FIG. 4B show an embodiment comprising a magnet 2 permanently attached or affixed to the whistle 1 and a magnetically attractive metallic base component 6 permanently affixed or attached to a metallic or non-metallic finger sleeve 3. The metallic base or docking component permits the finger sleeve to be constructed of magnetic or a variety of non-magnetic material, such as stainless steel, plastic, fiberglass, or other products.
FIG. 5A and FIG. 5B show an embodiment comprising a magnetically attractive metallic component 7 permanently attached to the whistle 1 and a magnet 2 permanently affixed or attached to the finger sleeve 3, which can be made of a magnetic or non-magnetic material.
FIG. 6A and FIG. 6B show an embodiment comprising a magnet 2a permanently attached or affixed to the whistle 1 and a second magnet 2b permanently affixed or attached to a finger sleeve 3, such as by fasteners 5 or otherwise. The sleeve 3 can be made of a magnetic or non-magnetic material.
FIG. 7A and FIG. 7B show an embodiment comprising a magnetically attractive metallic whistle 1 detachable from a magnet 2 permanently affixed or attached to a finger sleeve 3, such as by fasteners 5 or otherwise. The sleeve 3 can be made of a magnetic or non-magnetic material.
FIGS. 8A-8E show embodiments comprising a magnet 2 permanently attached or affixed to an intermediate base component, or magnet holding component 8. The base component 8 can be contoured to fit the configuration of a part of an existing whistle 1 and can be permanently attached or affixed to the existing whistle. The base component 8 can have any suitable shape, such the embodiment shown in FIGS. 8A and 8B, or the embodiment shown in FIGS. 8C and 8D. As shown in FIG. 8E, the intermediate base component 8 can also be configured to include two or more magnets 2 to provide for docking the whistle in multiple directions on a sleeve. As shown in FIGS. 8A-8E, the intermediate base 8 can be permanently affixed to a whistle body 1 or the magnet can be integrated or cast into the body of the whistle component. The shape of the intermediate base component 8 can be cast into the form of a whistle or the whistle can be configured in a shape that includes a platform for mounting a magnet.
FIGS. 9A-9E show embodiments comprising a magnetically attractive metallic component 7 attached to a separate base component 8 that is contoured to fit the configuration of the base of a whistle 1 or adapted to fit the base of an existing whistle. A sleeve 3 can include a permanently affixed magnet 2 for detachable coupling to the magnetically attractive metallic component 7. As shown in FIG. 9E, the intermediate base component 8 can also be configured to include a magnetically attractive metallic component 7a contoured to provide for docking the whistle in multiple directions. As shown in FIGS. 9A-9E, the intermediate base 8 can be permanently affixed to a whistle body 1 or the magnet can be integrated or cast into the body of the whistle component. The shape of the intermediate base 8 can be cast into the base form of a whistle or the whistle configured in a shape that includes a platform for mounting a magnet.
An adapter does not need to include a structural piece and a separate magnetic piece affixed together, as described for example in FIGS. 8A-9D. For example, any of the adapters 8 can comprise a one-piece adapter that is comprised or formed out of a magnet or magnetic material (e.g., ferrous metal) shaped in the form of an adapter for receiving a whistle.
FIG. 10A shows an embodiment comprising a magnetically attractive metallic component 6 permanently attached or affixed to a magnetically attractive or magnetically non-attractive metallic finger sleeve 3. The magnetically attractive metallic component 6 may be configured and/or contoured with a cavity and/or raised area to prevent the whistle from rotating and/or sliding from side to side. FIG. 10B shows an embodiment comprising a magnet 2 permanently attached or affixed to a magnetically attractive or magnetically non-attractive metallic or non-metallic finger sleeve 3.
FIG. 10C shows an embodiment comprising a magnetically or non-magnetically attractive finger sleeve component 3 with a permanently affixed or attached magnetically attractive metallic base component 6 and with a cushioning material 9 (e.g., foam rubber, or any various synthetic elastomers, such as silicone rubber, etc.) attached to and/or covering the finger sleeve component. FIG. 10D shows an embodiment comprising a magnetically or non-magnetically attractive finger sleeve component 3 with a permanently affixed or attached magnet 2 and with a cushioning material 9 attached to the finger sleeve component.
A whistle can be attached to a magnet as shown in FIGS. 2A, 2B, and a separate magnet can also be attached to a sleeve, such as with an adhesive, mechanical, or integral method. A sleeve with the permanently attached magnet permits the use of a whistle with another magnet attached or the use of a magnetically attractive metal whistle without a magnet attached.
The whistle 1 may comprise a plastic “pea whistle” or a plastic “pea-less whistle” or a “metal whistle” or any number of other whistle types, materials, and shapes.
The magnet 2 may be round, square, rectangular, or other shape and if mechanically attached, may have a hole with a countersunk hole for a flat headed screw 5 or bolt, for flush mounting.
The finger sleeve 3 can comprise a metallic material that is attracted to a magnet (any ferrous metal, such as steel) or can comprise a non-magnetic material such as plastic or aluminum, or other material, and can include a permanently attached metallic base, as shown in FIG. 4A and FIG. 4B.
In some embodiments, a kit can be provided that comprises one or more components that can be used to detachably magnetically mount a conventional whistle to a sleeve. For example, a kit can include a sleeve component and a coupling component, where the coupling component is shaped or configured to receive a whistle (plastic, metal, or any type) in a permanent or semi-permanent manner. The coupling component can have a concavity to allow a whistle to snap-fit into the concavity, for example, or may comprise flexible material that can be stretched around the whistle to hold the whistle together with the coupling component, or adhesives or fasteners can be used to affix the coupling component to a whistle. The assembly can include a detachable magnetic interface between the sleeve component and the coupling component, as discussed in various embodiments herein, so that the whistle/coupling component sub-assembly can be repeatedly detached from and reattached to the sleeve component, such as by using one's teeth or lips while the sleeve remains on one's hand or fingers.
Embodiments with Encased or Enclosed Magnetic Members
In some embodiments, a detachable whistle assembly can comprise a whistle/whistle adapter component and a base component with each of the two components comprising encased or enclosed magnets and/or magnetically attractive components (collectively referred to as “magnetic members”). One or both of the magnetic members can comprise a magnet so that the two components are magnetically attracted to each other. Exemplary embodiments are shown in FIGS. 11-18.
In some embodiments, the whistle/whistle adaptor component of such an assembly can be fabricated with separate polymeric parts that are attached to a polymeric whistle or fabricated integrally as part of a polymeric whistle. In some embodiments, the whistle and the adaptor component that holds one of the magnetic member are integrally formed or are manufactured as a single unit. For example the whistle housing can include two halves that are fixed together during manufacturing, and the two halves can include a portion that forms a housing for one of the magnetic member, such that when the two halves are secured together they contain the magnetic member.
FIGS. 11-16C illustrate an exemplary detachable whistle assembly 10 that comprises a whistle 12 with mouthpiece 14, an adaptor or neck 16, and a finger sleeve base component 24. The adaptor 16 can be integral with the whistle 12 or a separate piece that is attached (e.g., with an adhesive or weld or fastener) to the whistle 12. As shown in FIGS. 12-14, the adaptor 16 in this embodiment comprises two parts 18 and 20 that join together to form an enclosed cavity 34/40 permitting the insertion of a magnetic member 22, either during the assembly of the parts or integrally during the whistle fabrication process. Inserting a magnetic member in the cavity 34/40 can improve assembly time and can eliminate the need for fasteners and/or adhesives to attach the magnetic member to the whistle neck and/or whistle.
The adapter parts 18 and 20 can have similar but mirrored shapes, as shown, or other complementary shapes to form the adaptor 16. The adapter part 20 (FIGS. 13A-13D) includes cavity 34, surface 35 for attaching to a surface of the whistle 12, opening 36 to allow insertion of a loop (e.g., loop 32 in FIG. 12) projecting from the whistle body, and peg 38 configured to extend through the loop 32. The adapter part 18 (FIGS. 14A-14D) includes cavity 40 that cooperates with the cavity 34 to house the magnetic member 22, surface 41 that cooperates with the surface 35 for attaching the adapter to a surface of the whistle 12, opening 42 that cooperates with opening 36 to allow insertion of the loop 32 of the whistle into the adapter, and peg 44 that cooperates with peg 38 to extend through the loop 32 and retain the whistle. The two parts 18 and 20 can be glued, welded, fastened, or otherwise attached together.
After assembly or fabrication of the whistle and adapter, the magnetic member 22 can be fully encased and not exposed, or can be only minimally exposed, to view or weathering elements. The magnetic member 22 inserted into the encased adapter 16 may or may not be visible, or can be only minimally visible, which can provide a unique and single material appearance.
Utilizing a magnetic member with a stronger or weaker pull force rating permits the force required for removing the whistle neck/whistle component from the base component to be increased or decreased. Variation in the thickness of the portion of the adapter 16 (e.g., bottom of parts 18 and 20) that is between the magnetic member 22 and the base component of the assembly can permit adjustment (increase or reduction) of the pull force required to remove the whistle from the base component, which can be limited when utilizing stronger or weaker magnets or with a direct magnet to magnet or magnet to magnetically attractive component design. Variation in the surface texture of the portion of the encasement that is between the magnetic member 22 and the base component of the assembly can permit adjustment of the horizontal and/or rotational movement of the whistle relative to the base which is not possible, or more difficult, with a direct magnet to magnet or magnet to magnetically attractive component design.
The base component 24 can be fabricated with one or more casing parts (e.g., casing parts 28 and 30 shown in FIG. 12, also shown in FIGS. 15 and 16) attached to a retaining elements, such as finger sleeve (e.g., element 25 in FIG. 12), or fabricated integrally with a retaining element. With either method of fabrication, the base component of the assembly can include a cavity permitting the insertion of a magnetic member (e.g., lower element 26 in FIG. 12) either during the assembly of the casing parts or integrally during the fabrication process of the base 24. Inserting the magnetic member in the cavity can improve assembly time and can eliminate or reduce the need for fasteners and/or adhesives to attach the magnetic member to the whistle neck and/or whistle.
FIGS. 15A-15B illustrate an exemplary upper casing part 28 and FIGS. 16A-16C illustrate an exemplary lower casing part 30. The part 28 includes an upper mating surface 50 that contacts the lower surface the adapter 16, a lower recess 54 that receives the magnetic member 26, and ribs or projections 52 that extend down on the sides of the magnetic member and around the entrapped portion of the finger sleeve 25 or other retainer element. The lower part 30 includes an inner surface 60 that abuts the finger sleeve 25 and lateral walls 64 that form recesses 62 configured to matingly receive the projections 52 of the upper part 28 around the sides of the finger sleeve 25 and magnetic member 26. Together, the parts 28 and 30 sandwich the magnetic member and the finger sleeve 25 and secure them in place.
After assembly or fabrication of the base component 24, the magnetic member 26 may be fully encased and not exposed to view or weathering elements, or can be substantially encased and only minimally exposed. The magnetic member 26 inserted into the encased parts 28, 30 can be not visible or only minimally visible, which provides a unique and single material appearance.
Utilizing a magnet with a stronger or weaker pull force rating in the finger grip base can permit the force required for removing the whistle neck/whistle component from the base component to be increased or decreased. Variation in the thickness of the portion of the encasement (surface 50 of part 28) that is between the magnet of the base component and the whistle adapter component of the assembly can permit adjustment (increase or decrease) of the pull force required to remove the whistle from the base component which is limited with utilizing stronger or weaker magnets or direct magnet to magnet or magnet to magnetically attractive component design.
The whistle 12, adapter parts 18 and 20, and/or casing parts 28 and 30 can comprise polymeric material, metallic material, and/or other sufficiently strong and suitable materials.
Variation in the surface texture of the portion of the encasement that is between the magnetic member of the base component and the whistle neck component of the assembly can permit adjustment of the horizontal and/or rotational movement of the whistle neck component relative to the base component which is not possible or is more difficult with a direct magnet to magnet or magnet to magnetically attractive component design.
For example, FIGS. 17A-17C show an exemplary finger grip base 70 that includes an upper base component 72 having a knurled pattern 76 that separates the magnetic member 26 inside the finger grip portion from the removable portion of the assembly (e.g., the whistle 12 and the adapter 16). A lower base component 74 mates with the upper component 72 to secure the magnetic member 26 to the finger grip 25.
FIGS. 18A-18C show another exemplary finger grip base 80 that includes a lower base component 84 and an upper base component 82 that curls around the upper edges of the magnetic member 26 and forms an upper opening above the magnetic member that receives a textured insert 86, such as comprising a soft rubber or other similar material. The textured soft insert 86 separates the magnetic member 26 inside the finger grip portion 80 from the removable portion of the assembly (e.g., the whistle 12 and the adapter 16). In addition to limiting the horizontal and/or rotational movement of the removable portion, the insert 86 can serve to cushion the force of the attachment and reduce noise associated with attachment. The insert 86 can be attached directly to the magnetic member and/or attached to the curled upper edges of the upper base portion 82.
While both the base component and the whistle/adapter component of the detachable whistle assembly with encased or enclosed magnetic member are desirably used together, it is possible and within the scope of this disclosure for the two detachable components to be used separately with any other variations of a detachable whistle design that include an exposed magnetic member.
